Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and in particular to a vertical temporary consolidation device for steel beams and main towers. Background Technology

[0002] In bridge construction, especially in complex projects such as long-span cable-stayed bridges and suspension bridges, the temporary connection between the steel beams and the main tower is a crucial element in ensuring construction safety and structural stability. During construction, the temporary connection device must reliably connect the steel beams to the main tower, bearing the weight of the steel beams, construction loads, and wind loads to prevent displacement or overturning. After the main bridge structure is completed, it must be easily removed to release internal structural forces and ensure the bridge's normal operation.

[0003] Currently, the commonly used temporary consolidation methods for steel beams and main towers in the industry mainly include pier consolidation, sand box consolidation, welding consolidation, and simple bolt anchoring. However, these existing technologies all have certain limitations: pier consolidation is greatly restricted by construction site conditions, and the erection and dismantling of piers are cumbersome, resulting in low construction efficiency; sand box consolidation has limited load-bearing capacity and is prone to settlement problems due to uneven sand compaction under heavy loads, making it difficult to guarantee stability; although welding consolidation provides reliable connections, it requires cutting operations during dismantling, which not only has a long construction period but may also damage the main structure of the main tower or steel beam, affecting structural durability; and simple bolt anchoring, due to the lack of effective pre-tightening force control, is prone to bolt loosening under long-term loads, leading to decreased consolidation reliability and potential safety hazards.

[0004] In addition, the force transmission paths of existing temporary consolidation devices are often unreasonable. Some devices have obvious stress concentration due to imperfect anchoring structure design, which can easily lead to local structural damage. At the same time, most devices lack symmetrical design of the embedded components and steel beam connection components, which can easily generate eccentric bending moments when prestress is applied, further reducing the overall stability and load-bearing capacity of the consolidation system.

[0005] Therefore, developing a simple, easy-to-install and disassemble, reliable load-bearing, uniform stress distribution, and non-damaging vertical temporary connection device between steel beams and main towers has become an urgent technical problem to be solved in the field of bridge engineering construction.

[0025] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a vertical temporary consolidation device for a steel beam and a main tower, including a pre-embedded component 100, a fixing component 200, a pre-embedded component 100, and a prestressed connection component 300. The pre-embedded component 100 is fixedly installed on the top of the pier of the main tower 400; the fixing component 200 is fixedly installed on the bottom plate of the steel beam 500; the prestressed connection component 300 connects the pre-embedded component 100 and the fixing component 200, and is used to generate prestress between the pre-embedded component 100 and the fixing component 200 through tensioning, thereby realizing the vertical temporary consolidation of the steel beam 500 and the main tower 400.

[0026] During construction, the pre-embedded component 100 is first embedded and fixed during the pouring of the concrete at the top of the main tower 400 pier. Subsequently, the fixing component 200 is welded or bolted to the base plate of the steel beam 500 at the factory or on-site. Finally, the upper and lower components are connected using the prestressed connection component 300 and tensioned. After tensioning, the prestress is locked in the system, thereby fixing the steel beam 500 to the pier top, forming a temporary consolidation.

[0027] This device transforms the complex consolidation structure into three single-function, clearly defined modules. The pre-embedded component 100 is responsible for anchoring to the foundation, the fixing component 200 is responsible for connecting to the superstructure, and the prestressed connection component 300 applies and maintains the clamping force. This modular design makes the force path clear and direct, greatly simplifying structural analysis and calculation. Unlike traditional passive connections relying on welding or ordinary bolts, this invention employs a prestressing tensioning active control mechanism. The prestress value can be precisely applied based on theoretical calculations, thereby achieving active and quantitative control of the consolidation force and ensuring the reliability and consistency of the consolidation effect. Simultaneously, the process can be monitored and supplemented with additional tension, ensuring high safety.

[0028] In this embodiment, the prestressed connection assembly 300 includes at least one set of prestressed anchoring units 310, an upper anchoring system 320, and a lower anchoring system 330. The prestressed anchoring unit 310 includes prestressed steel bars. The upper anchoring system 320 is used to anchor the upper end of the prestressed steel bars to the fixing assembly 200 connected to the steel beam 500. The lower anchoring system 330 is used to anchor the lower end of the prestressed steel bars to the embedded assembly 100 connected to the top of the main tower 400 pier.

[0029] Based on the above structure, construction workers will use multiple prestressed steel bars, each steel bar and its anchoring structures at both ends constituting an independent prestressed anchoring unit 310. In this embodiment, four sets of prestressed anchoring units 310 are provided, and the four sets of prestressed anchoring units 310 work together. Among them, the upper anchoring system 320 and the lower anchoring system 330 ensure that the prestress can be reliably transferred from the steel bar to the fixing component 200 and the embedded component 100.

[0030] In this embodiment, the prestressed steel bar is a precision-rolled threaded steel bar.

[0031] In this embodiment of the application, preferably, a sufficient number of anchoring units can be configured according to the actual load calculation to ensure support safety, and the systematic anchoring design can also ensure reliable force transmission.

[0032] In this embodiment of the application, the upper anchoring system 320 includes an upper prestressed steel anchor plate 321 and an upper prestressed steel anchor head 322. The upper prestressed steel anchor plate 321 is fixedly disposed on the fixing component 200; the upper prestressed steel anchor head 322 is installed on the upper end of the prestressed steel and cooperates with the upper prestressed steel anchor plate 321.

[0033] In the above structure, the upper prestressed steel anchor plate 321 is a thick steel plate with through holes, which is firmly welded to the fixing component 200. During tensioning, the upper prestressed steel anchor head 322 is tightened at the upper end of the prestressed steel bar and pressed tightly against the upper prestressed steel anchor plate 321 through the through holes, thereby transferring the tension force to the fixing component 200.

[0034] In a specific embodiment of this application, the upper prestressed steel bar anchor head 322 is composed of a nut and a washer.

[0035] The design of the upper anchoring system 320 allows the upper end of the prestressed steel bar to be stably anchored to the fixing component 200. During the subsequent tensioning of the prestressed steel bar, the upper prestressed steel bar anchor plate 321 and the upper prestressed steel bar anchor head 322 cooperate with each other to effectively bear and transfer the prestress, ensuring the stress stability of the connection between the steel beam 500 and the main tower 400.

[0036] Furthermore, in this embodiment, since there are four sets of prestressed anchoring units 310, in order to effectively tension the prestress, one upper prestressed steel anchor plate 321 is provided. Four through holes are provided on the upper prestressed steel anchor plate 321. The prestressed steel anchor head on each set of prestressed anchoring units 310 is pressed tightly onto the upper prestressed steel anchor plate 321 through the through holes, thereby transmitting the tension force to the fixing component 200.

[0037] In this embodiment, the lower anchoring system 330 includes a lower prestressed steel anchor plate 331 and a lower prestressed steel anchor head 332. The lower prestressed steel anchor plate 331 is fixedly installed on the pre-embedded component 100. The lower prestressed steel anchor head 332 is installed at the lower end of the prestressed steel bar and cooperates with the lower prestressed steel anchor plate 331.

[0038] The structural design of the lower anchoring system 330 echoes that of the upper anchoring system 320. The lower prestressed steel anchor plate 331 is also a thick steel plate with through holes, securely welded to the embedded component 100. During installation, the lower prestressed steel anchor head 332 is tightened at the lower end of the prestressed steel bar, pressing firmly against the lower prestressed steel anchor plate 331 through the through holes, transferring the tension force to the embedded component 100, and subsequently to the top of the main tower 400 pier. This design ensures that the lower end of the prestressed steel bar is stably anchored to the embedded component 100, forming a complete prestress transfer path together with the upper anchoring system 320.

[0039] In a specific embodiment, the lower prestressed steel anchor head 332 also consists of a nut and a washer, consistent with the upper structure, facilitating construction and quality control. Simultaneously, since four sets of prestressed anchoring units 310 are provided, the lower prestressed steel anchor plate 331 is also set as one, with four through holes to accommodate the tensioning requirements of the four sets of prestressed anchoring units 310. This symmetrical design not only improves the overall stability of the device but also ensures more uniform prestressing application, effectively avoiding the generation of eccentric bending moments.

[0040] In this embodiment of the application, the pre-embedded component 100 includes a pre-embedded steel plate 110 pre-embedded in the concrete at the top of the main tower 400 pier, and a pre-embedded connecting plate 120 vertically fixed on the pre-embedded steel plate 110, wherein the lower prestressed steel anchor plate 331 is fixed to the pre-embedded connecting plate 120.

[0041] In the above structure, the embedded steel plate 110 in the embedded component 100 is a large-area steel plate with a large number of anchor bars welded to its back to ensure that it can be firmly embedded in the concrete at the top of the pier. The embedded connecting plate 120 is vertically welded to the upper surface of the embedded steel plate 110. The lower prestressed steel anchor plate 331 is welded to this connecting plate.

[0042] When welding the lower prestressed steel anchor plate 331 to the embedded connecting plate 120, they can be connected and fixed by connectors or directly welded together to ensure that there is no relative displacement between the lower prestressed steel anchor plate 331 and the embedded connecting plate 120 during the subsequent prestressing tensioning process. This ensures that the prestress can be accurately transferred to the embedded steel plate 110 and then to the pier top structure of the main tower 400.

[0043] In this embodiment of the application, the pre-embedded component 100 further includes multiple pre-embedded stiffening plates 130, which are disposed in the angled area formed by the pre-embedded steel plate 110 and the pre-embedded connecting plate 120, and are fixedly connected to the pre-embedded steel plate 110 and the pre-embedded connecting plate 120 respectively.

[0044] The embedded stiffening plate 130 adopts a triangular steel plate structure, wherein the triangle is a right triangle, and the two right-angled sides of the right triangle are welded and fixed to the embedded steel plate 110 and the embedded connecting plate 120 respectively. This stiffening plate design can significantly enhance the connection strength between the embedded steel plate 110 and the embedded connecting plate 120, and effectively resist the local stress concentration phenomenon generated during the prestressing tensioning process.

[0045] In practical engineering applications, multiple stiffening plates are typically evenly distributed in the angled area. The specific number is calculated and determined based on the number of prestressed anchoring units 310 and the magnitude of prestress. Through this reinforced design, the embedded component 100 can better withstand the tensile and bending moments generated during prestress transfer, ensuring the stable and reliable stress performance of the entire vertical temporary consolidation device. Simultaneously, the presence of the stiffening plates effectively prevents deformation of the embedded steel plate 110 and the connecting plate during concrete pouring, ensuring the geometrical accuracy of the embedded component 100 and providing a reliable foundation for the precise installation of subsequent prestressed steel bars.

[0046] The embedded stiffening plate 130 greatly enhances the stiffness and strength of the embedded component 100 at critical stress nodes. The stiffening plate effectively resists the huge bending moment and shear force generated by prestress, prevents the connecting plate from bending or tearing, ensures the robustness of the node area, and thus improves the safety reserve of the entire device.

[0047] In this embodiment, preferably, since the main tower at the bottom bears the total mass of the steel beam, an additional layer of embedded steel plate 110 can be set on the embedded connecting plate 120, forming two layers of embedded steel plates 110. Each layer of embedded steel plate 110 is equipped with an embedded stiffening plate 130. This double-layer embedded steel plate 110 design further enhances the load-bearing capacity and stability of the embedded component 100. The two layers of embedded steel plates 110 are fixed together by welding or other reliable connection methods. Each layer of embedded steel plate 110 is equipped with a corresponding embedded stiffening plate 130. These embedded stiffening plates 130 also adopt a triangular steel plate structure and are welded and fixed to the upper and lower layers of embedded steel plates 110 and the embedded connecting plate 120, respectively. Through this design, the embedded component 100 can better disperse and transmit the tensile force and bending moment generated by the prestress, effectively preventing structural damage caused by local stress concentration. Meanwhile, the double-layer embedded steel plate 110 also improves the fatigue resistance of the device, extends its service life, and provides more reliable and durable support for the vertical temporary consolidation of the steel beam 500 and the main tower 400.

[0048] In this embodiment of the application, the fixing component 200 includes a top steel plate 210 welded to the bottom plate of the steel beam 500, and an upper steel plate connecting plate 220 vertically fixed below the top steel plate 210, wherein the upper prestressed steel anchor plate 321 is fixed to the upper steel plate connecting plate 220.

[0049] The top steel plate 210 serves as a transition structure between the fixing component 200 and the upper steel plate connecting plate 220, and is made of high-strength steel.

[0050] During welding, the weld quality between the top steel plate 210 and the bottom plate of the steel beam 500 must be ensured. A full penetration welding process must be employed, and non-destructive testing must be performed to prevent welding defects from affecting structural strength. The upper steel plate connecting plate 220 is vertically welded below the top steel plate 210, its position corresponding to the embedded connecting plate 120 in the embedded component 100, providing a stable installation foundation for the upper prestressed steel anchor plate 321. The length and width of the upper steel plate connecting plate 220 are designed according to the number and arrangement requirements of the prestressed anchoring units 310 to ensure accurate anchoring of each group of prestressed steel bars.

[0051] When welding the upper steel plate connecting plate 220, its verticality and flatness must be strictly controlled to avoid uneven prestress transmission due to installation deviations. The upper prestressed steel bar anchor plate 321 is fixed to the upper steel plate connecting plate 220 by high-strength bolts or welding. Its installation position must be consistent with the lower prestressed steel bar anchor plate 331 in the vertical direction to ensure a straight transmission path for the prestressed steel bars. This structural design enables the fixing component 200 to effectively bear the tensile force transmitted by the prestressed steel bars and distribute the force evenly to the bottom plate of the steel beam 500, avoiding damage to the steel beam 500 structure caused by local stress concentration. At the same time, the overall stiffness of the fixing component 200 is significantly improved, and it can maintain a stable geometric shape during prestressing tensioning, ensuring the connection accuracy between the steel beam 500 and the main tower 400.

[0052] In this embodiment of the application, the fixing component 200 further includes multiple top stiffening plates 230, which are disposed in the angled area formed by the top steel plate 210 and the upper steel plate connecting plate 220, and are fixedly connected to the top steel plate 210 and the upper steel plate connecting plate 220 respectively.

[0053] The top stiffening plate 230 also adopts a triangular steel plate structure, consistent with the design of the pre-embedded stiffening plate 130. The top stiffening plate 230 is firmly welded to the top steel plate 210 and the upper steel plate connecting plate 220 through its right-angled sides, forming a stable triangular support system.

[0054] In practical applications, the size and thickness of the stiffening plates need to be designed according to the stress characteristics of the fixing component 200. High-strength steel of the same material as the main structure is typically used to ensure its coordinated operation with the overall structure. By rationally arranging multiple stiffening plates, the connection stiffness between the top steel plate 210 and the upper steel plate connecting plate 220 can be effectively enhanced, significantly improving the deformation resistance of the fixing component 200 during prestress transfer. This reinforced design not only helps to disperse the local tensile stress generated by the prestressed steel bars, preventing cracks or deformation at the connection points, but also enhances the overall stability of the fixing component 200, ensuring precise geometric dimensions even in complex construction environments.

[0055] Meanwhile, the presence of the stiffening plate also improves the fatigue performance of the fixing component 200, enabling it to better withstand repeated loads and extend the service life of the entire vertical temporary consolidation device. Through this systematic reinforcement design, the fixing component 200 and the embedded component 100 together form a prestressed transfer system with matched stiffness and reasonable stress distribution, providing double protection for the reliable connection between the steel beam 500 and the main tower 400.

[0056] In this embodiment, the embedded connecting plate 120 and the upper steel plate connecting plate 220 are vertically opposite each other, and the prestressed steel bars are vertically tensioned between the embedded connecting plate 120 and the upper steel plate connecting plate 220.

[0057] During construction, ensure that the vertical projections of the pre-embedded connecting plate 120 embedded in the pier top and the upper steel plate connecting plate 220 welded to the bottom of the steel beam 500 coincide or substantially coincide. In this way, the prestressed steel bars can be tensioned vertically between the two.

[0058] It ensures that the prestressed steel bars are in the optimal vertical stress state, avoids additional bending moments caused by misalignment, and enables the prestress to be converted into the vertical clamping force on the steel beam 500 most effectively, thus improving the efficiency and reliability of the device.

[0059] In this embodiment, the multiple top stiffening plates 230 of the fixing component 200 are evenly spaced along the length of the upper steel plate connecting plate 220.

[0060] In the above structure, a pair of top stiffening plates 230 are provided at regular intervals along the length of the upper steel plate connecting plate 220. This distribution is uniform and continuous.

[0061] By uniformly arranging stiffening plates, continuous and uniform support is provided for the upper steel plate connecting plate 220, avoiding the occurrence of local weak points. This ensures that regardless of where the prestressed anchor point is set on the connecting plate, there is sufficient rigidity support underneath, making the structure more uniform and reasonable in terms of stress distribution.

[0062] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
